The key target network of cervical decoction was found in the treatment of cervical cancer, in which the TGFβ1 signaling pathway, HIFa-1 signaling pathway, proteoglycan in cancer, and Th17 cell differentiation are considered as important gene targets, and these genes are all related to the regulation of immune system, which directly participates in tumor regulation pathway. This evidence concerns the gene TGFB1 and neoplasm.
